1:30 p.m.

A group of people working as security officers for Dakota Access pipeline opponents are telling protesters gathered on a North Dakota highway near a construction site to return to the main camp.

The order came as authorities prepared to remove two roadblocks created overnight by protesters, one comprised of a burned SUV and sheets of plywood, and another with two heavy trucks on a bridge.

Camp security told the group of about 50 people that tribal leaders wanted protesters to leave the site. Some still remained.

The protesters also defied authorities” earlier orders to clear the roadway, which is in a rural part of the state. The Highway Patrol had already shut down traffic to keep vehicles away from the protest area.

About 200 officers in riot gear are standing guard behind the armored vehicles.

Protesters who were ousted from a camp they established on private land in North Dakota to protest the construction of the Dakota Access oil pipeline are using burned vehicles to block a state highway.
